a) What would you see if you ran a Thin Layer Chromatography (TLC) on a mixture of the three solids shown below using silica gel as the stationary phase and ethyl acetate/hexanes as the mobile phase? Whichsolid would have the highest Rf and which would have the lowest Rf? Explain b) Would changing the mobile phase (from part a) and increasing thepolarity by introducing small amount of methanol to the mobile phase change the order ofRf of the above 3 compounds? Explain c) Another type of chromatography is Reverse Phase Chromatography. In this type ofchromatography, the stationary phase is non-polar and the mobile phase is polar. If astudent performed Reverse Phase TLC on the mixture of 3 solids (from part a),what would be the order of Rf’s of the compounds? Which would have the lowest Rf andwhich would have the highest Rf?

1. In thin layer chromatography (TLC), explain how the pigments separate on a piece of paper. 2. If the spots are colorless on a TLC plate, how can you make it visible? Enumerate 2 ways and discuss each.
TLC was used to compare the solubility of two compounds A and B in a solvent system (acetic acid, methanol, H2O). The distances that solvent has moved in the silica gel TLC was 12 cm. and for the compounds were 2 and 8 cm respectively.

a) Thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) can be used as examples to explain difference between adsorption and partition. For each of these chromatographic techniques, identify: + the stationary and mobile phase + how the mobile phase moves b) How is the Rf value for a spot on a TLC plate calculated? What can the Rf value be used for? In order to achieve the best separation of several components of different polarity in a mixture spotted on a TLC plate, what guideline should one follow regarding the choice of a developing solvent? (i.e. polar, non-polar, etc.)
A student spots an unknown sample on a TLC plate and develops it in dichloromethane solvent. Only one spot, for which the Rf value is 0.95, is observed. Does this indicate that the unknown material is a pure compound? What can be done to verify the purity of the sample?
The three TLC plates below show the analysis of the same mixture of two compounds. One plate was developed in 100% DCM, one in 90:10 DCM/MeOH, and one in 80:20 DCM/MeOH. Determine which plate was developed in which solvent.
You are an aquatic scientist and tasked to sample water that contains chlorophenols for gas chromatographic analysis from your local waste water treatment plant (WWTP). Using knowledge of sample preparation and chromatograph, how would you sample, preserve and prepare these samples for GC analysis and why GC is the best detection technique?
Thin Layer Chromatography why the non-polar compounds move up the plate most rapidly (higher Rf value), whereas polar substances travel up the TLC plate slowly or not at all (lower Rf value)? Please help me explain this question! Thank you so much!
